Summer sky filled with three dozen meteors from the annual Perseid meteor shower of 12 August 2023. The meteors all appear to be streaking away from the radiant point in Perseus at far left. The location is the upper viewpoint near the Park Entrance, and looking northeast to southeast. The lights in the valley below are from the campground and service centre. The one glaring sodium vapour light should be removed or at least shielded. The brightest horizon glow at right is from Medicine Hat. Some bands of green and red airglow tint the sky naturally. The meteor trails nicely demonstrate the green to red transition in their colours as they descend into the atmosphere and burn up. Photographed from the badlands of Dinosaur Provincial Park, in the Red Deer River valley in Alberta, Canada.
